RNA Interference for Viral Infections [PDF]

Current Drug Targets, 2012
The treatment of viral infections has relied on pre-emptive vaccination or use of a limited range of anti-viral drugs. However, the majority of viruses have no available drugs and treatment is merely supportive. RNA interference (RNAi) offers the ability to directly and rapidly treat virus infections via the targeting of viral genes.

Enhanced inflammation and suppressed adaptive immunity in COVID-19 with prolonged RNA shedding

Cell Discovery, 2022
Little is known regarding why a subset of COVID-19 patients exhibited prolonged positivity of SARS-CoV-2 infection. Here, we found that patients with long viral RNA course (LC) exhibited prolonged high-level IgG antibodies and higher regulatory T (Treg ...

A novel mechanism underlying the innate immune response induction upon viral-dependent replication of host cell mRNA: A mistake of +sRNA viruses' replicases [PDF]

, 2017
Viruses are lifeless particles designed for setting virus-host interactome assuring a new generation of virions for dissemination. This interactome generates a pressure on host organisms evolving mechanisms to neutralize viral infection, which places the

Viral suppression of RNA silencing [PDF]

Science China Life Sciences, 2012
يلعب إسكات الجينات (إسكات الحمض النووي الريبي) دورًا أساسيًا في الدفاع المضاد للفيروسات في النباتات والفطريات واللافقاريات. تقوم الفيروسات بتشفير البروتينات التي تمنع إسكات الجينات لمواجهة دفاع المضيف. تم تحديد المثبطات الفيروسية لإسكات الحمض النووي الريبي (RSVs) من جميع الفيروسات النباتية تقريبًا التي تولد وبعض فيروسات الحشرات والثدييات. كشفت الدراسات

Nucleocapsid protein captures DDX5 and RNMT facilitating viral RNA synthesis and viral protein translation for coronavirus replication

mBio
Coronaviruses (CoVs) hijack host RNA-binding proteins (RBPs) to facilitate their replication, but the viral proteins and host RBDs that participate in the synthesis of viral RNA and protein are unclear.

Reovirus Nonstructural Protein σNS Recruits Viral RNA to Replication Organelles

mBio, 2021
The function of the mammalian orthoreovirus (reovirus) σNS nonstructural protein is enigmatic. σNS is an RNA-binding protein that forms oligomers and enhances the stability of bound RNAs, but the mechanisms by which it contributes to reovirus replication

Isolation of poliovirus 2C mutants defective in viral RNA synthesis [PDF]

, 1988
Two poliovirus mutants were isolated that contain an oligonucleotide linker insertion in the 2C-coding region of the viral genome. One, 2C-31, has a strongly temperature-sensitive phenotype and the other, 2C-32, forms small plaques on HeLa cell ...

Viral noncoding RNAs: more surprises [PDF]

Genes & Development, 2015
Eukaryotic cells produce several classes of long and small noncoding RNA (ncRNA). Many DNA and RNA viruses synthesize their own ncRNAs. Like their host counterparts, viral ncRNAs associate with proteins that are essential for their stability, function, or both.

The DEAD-box RNA helicase DDX6 is required for efficient encapsidation of a retroviral genome.

PLoS Pathogens, 2011
Viruses have to encapsidate their own genomes during the assembly process. For most RNA viruses, there are sequences within the viral RNA and virion proteins needed for high efficiency of genome encapsidation.
